Chinese stock indices categorize companies based on their market capitalization, with indices like the CSI 2000 representing smaller firms within the dynamic A-share market. Notably, as of mid-2023, the CSI 2000 has drawn less attention and allocation from both retail investors and institutional funds compared to its larger counterparts. Despite witnessing a modest gain this year, the CSI 2000 continues to be a point of curiosity for market analysts.

On August 11, 2023, the China Securities Index Co. made a notable announcement by officially launching the CSI 2000 Index. Concurrently, ten leading fund companies, including prominent names like E Fund and Huaxia Fund, submitted applications for a new CSI 2000 ETF. This dual announcement occurred when the A-share market was in a period of adjustment, creating an environment that called for an influx of new capital to energize market sentiment.

Evaluating the performance throughout the year, the CSI 2000 has shown itself to be relatively resilient. As of August 29, the index reported a 3% increase since the start of 2023. In stark contrast, other indices like the CSI 300, CSI 500, and CSI 1000 had recorded declines of -2.11%, -1.61%, and -2.75%, respectively. Moreover, over the past two years, the CSI 2000 has also exhibited stronger stability, with a decrease of just -4.73%, while the larger indices stumbled with declines ranging from -19.63% to -21.48% during the same period.

While discussing investment patterns, it is worth noting that the Northbound capital inflow—representing investments made by foreign investors in the Chinese A-share market—registered the lowest holding proportion in the CSI 2000 among several indices, standing at merely 0.45% by the end of the first half of the year.

What, then, distinguishes the CSI 2000? The investment landscape from public offerings and foreign capital provides fascinating insights. The substantial difference in sectoral structure and valuation comparisons highlight the uniqueness of the CSI 2000.

When examining market scale, the CSI 2000 contains the highest number of constituent stocks compared to other indices yet represents the smallest total market capitalization. By mid-2023, the total market capitalization of CSI 2000 stocks reached 7.25 trillion yuan, which is merely 19.04% of the CSI 300's market cap and 65.63% and 73.07% of those of the CSI 500 and CSI 1000, respectively. Consequently, the larger indices wield greater financial heft, as demonstrated by their market capitalizations of approximately 38.08 trillion yuan, 11.05 trillion yuan, and 9.92 trillion yuan.

In terms of sector composition, the CSI 2000 encompasses 30 industries beyond banking, with the leading three sectors being Machinery, Computer Technology, and Electronics. By the end of the first half of the year, these three sectors accounted for 12.28%, 7.99%, and 7.76% of the index's total market capitalization.

In comparison, the CSI 300 spans 29 sectors while excluding the Comprehensive and Environmental sectors, wherein the three top-performing sectors are Banking, Food and Beverage, and Non-bank Financials. Their market caps constituted 16.84%, 11.35%, and 9.03%, respectively. Similarly, the CSI 500 and CSI 1000 indices encompass all 31 industries, with their predominant sectors being Pharmaceuticals and Electronics.

However, in valuations and return on equity (ROE), the CSI 2000 does not boast a competitive advantage. As of late August, the price-to-earnings (P/E) ratio for the CSI 2000 stood at 57.57, significantly outweighing those of the CSI 300, CSI 500, and CSI 1000, which were at 11.65, 22.92, and 35.89, respectively. The price-to-sales (P/S) ratio for the CSI 2000 was 1.73, while the P/B ratio registered 2.30, putting it at a disadvantage in terms of valuation metrics.

When it comes to public fund investments in the CSI 2000, noticeable underweighting persists. Fund types have been diversifying their allocations, though the aggregate level remains decidedly low.

As for major stocks held by public funds, by the end of Q2 2023, there were 810 CSI 2000 stocks being actively held, constituting 40.50% of the index's total components. This figure marked a slight increase from 40.40% in the previous quarter. The public fund's holdings in terms of market value rose to 923 billion yuan, up by a significant 25.58% compared to earlier in the year.

While the proportion of the CSI 2000 in public fund assets grew to 3.24%, it still lagged behind the overall market weight of 10.20%. Essentially, this reflects a shortfall of 6.96 percentage points. Instead, heavyweight indices like the CSI 300 captured 67.41% of public fund assets, indicating a continued preference for larger market caps.

The situation persists despite a marginal uptick in overall holdings in certain sectors like the CSI 500 and CSI 1000. Interestingly, the CSI 300 has maintained its status as the only sector experiencing over-allocations, while the others have seen a continuous rise in allocations.

According to data from Dongfang Caifu, public fund holdings in the CSI 2000 enjoyed a 21.44% appreciation from the end of the previous year. Nevertheless, their weights remain relatively low compared to broader market indices.

Thus, overwhelming interest in more established indices leaves the CSI 2000 in a favorable yet under-appreciated position within the A-share arena. It ultimately represents the potential for future growth, yet still wrestles with investor hesitance and meager foreign fund interest.

On the front of northern capital flows, the CSI 2000 ranks last, with a holding value of merely 326 billion yuan and a holding ratio of just 0.45%. However, there are signs of improved interest and investment from foreign capital.

Notably, among the 2,000 constituent stocks in this index, merely 705 are eligible for foreign investment through Stock Connect, resulting in underrepresentation by foreign investments. The distribution of leading industries reveals Mechanical Equipment, Power Equipment, and Media as top sectors by Northbound capital value. Overall, the increasing flow of foreign capital indicates an evolving sentiment indicated by a 4.02-fold increase since the start of the year.

In summary, while the CSI 2000 remains entrenched as a small-cap play within the broader segment of A-shares, its potential trajectory is contingent upon evolving investment strategies from both domestic and foreign funds alike.
